There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Athanasios NenesBacteria in the soil can hitch a ride on raindrops and be deposited into the air once the drops pop, according to a recent study in Nature Communications. Under the right wind conditions, some of these bacteria could be lifted even higher into the sky. But what happens once microbes are in the atmosphere? Atmospheric chemist Athanasios Nenes, a professor with the School of Earth and Atmospheric Sciences and the School of Chemical and Biomolecular Engineering, is currently collecting samples of the airborne microbiome in the troposphere five to nine miles above the Eastern Mediterranean. So far he has found a mix of 17 different taxa of bacteria. Nenes, along with EAS professor Rodney Weber and other researchers, also helped develop a unique instrument to measure bioavailable phosphate ions in atmospheric particles. Bioavailable phosphate can act as a fertilizer for the oceans, with profound impacts for ocean life and the carbon cycle.
